The study of endocrine cancers and oncology focuses on tumors affecting hormone-producing glands such as the thyroid, pancreas, and adrenal glands. Malignancies like pancreatic neuroendocrine tumors and medullary thyroid carcinoma require specialized treatment approaches due to their complex interaction with hormonal regulation. Advances in molecular oncology have led to targeted therapies that inhibit abnormal signaling pathways, improving survival rates. Immunotherapy is also gaining traction as a promising approach for endocrine cancers, particularly in cases resistant to traditional chemotherapy. Early detection through biomarker screening and imaging technologies enhances treatment efficacy. Ongoing research continues to refine therapeutic options, providing hope for improved patient outcomes.
